Okay,
just a quick one as I didn't have anything in reserve. Shouldn't prove outrageously difficult (with apologies to The Prodigy...

)
I'm a firestarter, angry firestarter.
At gates of doom I saw too soon,
The slaughter and disaster.
White from blue, no minstrel, true.
Torchbearer and light caster.
Ninth in line, renown is mine,
But student beats the master.
Guess on!
